Thigh injury rules England's Wood out of fourth day against Sri Lanka

The 34-year-old Durham quick left the field at Old Trafford just two balls into his 11th over late on Friday.

Following an assessment by England medical staff, the injury-prone paceman has been advised to rest.

England will hope they can still go 1-0 up in this three-match series without Wood's express speed, with Sri Lanka resuming on 204-6 in their second innings -- a lead of just 82 runs.

An England and Wales Cricket Board statement said: "England pace bowler Mark Wood has sustained a right thigh muscle injury late on the third day of the first Test against Sri Lanka at Old Trafford.

"He will not return to the field today and will continue to be assessed by the England medical team to determine the full extent of the injury."
